THE NEW NATURE
Having been born again, not of corruptible seed but incorruptible, through the word of God which lives and abides forever.
~ 1 PETER 1:23
When we become Christians we are not remodeled, nor are we added to—we are transformed. Christians don’t have two different natures; we have one new nature, the new nature in Christ. The old self dies and the new self lives; they do not coexist. Jesus Christ is righteous, holy, and sanctified, and we have that divine principle in us, what Peter called the “incorruptible” seed (1 Pet. 1:23). Thus our new nature is righteous, holy, and sanctified because Christ lives in us (Col. 1:27).
Ephesians 4:24 tells us to “put on the new man,” a new behavior that’s appropriate to our new nature. But to do so we have to eliminate the patterns and practices of our old life. That’s why Paul tells us to “put to death your members which are on the earth: fornication, uncleanness, passion, evil desire, and covetousness” (Col. 3:5).
